Thanks for sharing the video DOHC, I never saw it before. I like some of his music and his radio show most of the time but he's an America hating communist. It makes me happy so see how douchey he used to dress.

And you're right on everything about ethanol except for the performance end of it. A lot of guys are building high performance e85 motors because of the cheapness and readily available fuel. You throw a lot of compression and timing at them and them and they do well with it. Plus you don't have to worry about flushing your fuel system every time you park like with straight methanol and it doesn't wash the cylinder walls as bad either.

But anyways, to the original topic, I would cut your head down for mote compression. I'd imagine you could get a 1st gen Tecate head for $10-20 if you want to go back to stock
